蓝牙音频输入模拟输出是最常见的方式。 也可以再此基础上动态切换输入方式。 针对TX切换EQ,调节音量不能出提示声音问题可以增加本地提示声音然后混合mix到a2dp audio然后在BT(sink)端出提示声音。
提示声音播放接口如下 void appKymeraHandleInternalTonePromptPlay(const KYMERA_INTERNAL_TONE_PROMPT_PLAY_T *msg) { kymeraTaskData *theKymera KymeraGetTaskData(); output_source_t output {0}; int16 volume_db (msg-tone ! NULL) ? KYMERA_CONFIG_TONE_VOLUME : KYMERA_CONFIG_PROMPT_VOLUME;
